    Depending on the vest that may not even be needed. An Aerostich vest has the 2 wire SAE / Tender connection, it plugs right in.

    Heck, yeah! As long as the cable is long enough, good to go... just don't forget to unplug before you walk away for coffee!

    I want an R2 real bad so I'm reading a bunch.

    Check the parts changes by year here... http://www.rickramsey.net/WR250Rmods.htm
    Looks like twice it was up-graded and the better is for 2012.

    Manual adjuster here... http://www.advrider.com/forums/showthread.php?t=782813

    Little something here... http://wr250rforum.forumotion.com/t7876-manual-timing-chain-tensioner


    I will buy used and would consider a manual type at the first sign of chain noise. Just me though. My K75s makes a racket but it will be sold.

    After completing the TAT with 13/47 (too high; should have been 13/49) I changed the rear to a 45 and rode 2800 mile home in four days. Averaged 700 mi per day, but one was short due to 114 F heat, and the last was 900 miles. These little bikes will do it! Ran about 65 on the interstate all the way and had no problems. DID Gold x-ring chain, no adjustment the whole trip, and Ironman sprocket. Good combination. Just ran another 2200 mile ride on the 13/47 as it was mostly good gravel and pavement, and still no adjustment needed. Lube every day, whether it's needed or not.

    Powerlet offers a cable with a SAE plug at one end and a pigtail on the other end. Plug the SAE into your battery tender cable and jacket liner into the pigtail. $20

    Gerbing offers a jacket liner harness for $10. It has the pigtail plug. I bought two and spliced the second one running the pigtail to the bars for my GPS.

    Google up their websites.

    STOP!

    DO NOT use the pig tail that came with the tender.... it is very likely to have thinner gauge wires which could overheat with the increased heated gear amperage. Use a pig tail that is supplied with the heated gear. I recommend the ones from Warm and Safe.

    YMMV, just don't melt your harness... you will regret it.

    I changed to Kenda 761's in Oregon after using D606's on the TAT. The Kendas were great on the road, and barely showed any wear after getting home. I have them in the garage and will put them on during periods when not dual sporting. It sure made a difference runing down the superslab; smooth and quiet. And, my last post was incorrect. Last trip was with the 13/45. No need for lower gearing on that one.

    The battery tender pigtail has a 7 amp fuse in it, same rating as the jacket liner.
    I've run it hot enough to cook Hebrew Nationals for hours, never a problem.

    Just a quick little WR250R review. A mate and I rode them from Cairns to Cape York in far northern Australia where we did about 3200km on the bikes. They performed almost flawlessly. A couple of loose bolts here and there and my starter button packing it in. A little bit more power would have been nice in the soft sand and on the higher speed transport sections, but overall, I loved this bike for the job.

    Please clarify - do you mean the gearing you ran on the TAT was 13/45? Or only the dash home from Oregon?

    Thank you.

    One of my other hobbies is amateur radio, so I use Anderson Powerpole connectors for all my 12 VDC needs. The gender-less connector allows me to mix and match my cables however I need them.

    Just wouldn't want someone to think they could upsize the fuse in a common tender lead and think it was ok.

    Cheap insurance and a very good idea :nod

    Do it once, do it right and be done with it.

    Hey Riders,

    I'm picking up a set lines from Hel and I'm wondering if anyone has the exact length they used for a shortened front line on an X. I want to make sure there is enough for suspension travel, but you all know the stock one on there is way too long and hangs above the master cylinder in its OEM configuration.

    I saw the thread in WRR, but I didn't see any specific lengths. Thanks so much for your help.

    The leads shipped with my tender are 16 awg, probably the same as all of them. it's fair to point out that the amperage capacity for that gauge bundled into a loom or "enclosed" is ~13 amps. In "free air" [ not enclosed] the capacity is ~22 amps.

    All of us will, and do, effect the solution we deem best; in my case, I made a lead and am happy with the result. Others may choose a different path.

    Thanks for all the input on getting my bike ready to run an electric vest. I did some browsing on Aerostich last night and I think I found the perfect setup. This is what I'm planning to get:

    http://www.aerostich.com/sae-switch-coil-cord-kit.html

    It comes with the pigtail to connect to the battery, and it has a fuse in it. It also has a coiled cord with a switch, and then it has an extension. It seems like it has everything I need in one kit. Now I just have to decide if I want to get the Aerostich heated bib or a full vest. :1drink

    And now I found these:

    http://www.aerostich.com/aerostich-warm-wrap-grips.html

    I might get a splitter and run these too! I had the under the grip type heaters on my KLX, but they didn't work that great. Maybe these would work better.
